Patent EP-0275246-A2 (EP)
Inventor: LOVETRO DAVID C
IPC: B01J10/00
Filed: 1988-01-14
Abstract: In accordance with the practice of this invention there is provided an improved apparatus for the preparation of chlorine dioxide which employs an improved chlorine dioxide generator comprising a small reaction chamber (15) with means for injecting a concentrated metallic chlorate solution (35), a concentrated sulfuric acid solution (40), and gaseous sulfur dioxide (45). The sulfur dioxide gas is injected into the reaction chamber from the bottom through a porous medium (23) which disperses the gas as extremely fine bubbles into the aqueous reaction medium in the chamber. 
     The reaction chamber is equipped with an internal Teflon braided cooling coil (65) inserted therein which not only cools the reaction medium but also provides a tortuous path for the sulfur dioxide bubbles. By retarding the upward path of the bubbles, the sulfur dioxide is held in solution for a longer period of time allowing more time for reactant gas dissolution and corresponding chemical reaction. 
     The reaction chamber is maintained under superatmospheric pressure so that the chlorine dioxide that is produced is maintained in solution. Keeping the reaction chamber under pressure, as opposed to atmospheric pressure operation, also promotes sulfur dioxide solubility. Because the chlorine dioxide isn't handled in a separate gas phase, operation of the unit is more simple and inherently safer than prior art systems which handle chlorine dioxide as a gas.

Abstract: Method for processing of liquid manure and similar slurry materials which contain organic material as well as nitrogenous chemical substances. The method leads to the separation of the slurry material into a solid-matter phase and a liquid phase, which together contain the nitrogenous components. The degree of acidity of the slurry material is adjusted before separation. Both material phases are sterile. The liquid phase can be evaporated, and the water recovered from this process can be used for feeding purposes, while the concentrate can be combined and used together with the solid-matter phase as fertilizer. There is also described an apparatus with a separation tank (101,102) for the execution of the method. The separation tank has a discharge opening (105) for the liquid phase, a heating surface (106) connected to a heat source (107) for the heating of the pre-treated liquid manure (10), a solid-matter removal element (110, 112) and a liquid manure introduction element (118). Additionally, it can have a liquid manure pre-heat­ing heat exchanger (108), liquid manure sieves (109), liquid manure level control (111), liquid manure temperature control (119) and a solid-matter draining element, which ensure continuous operation.

Abstract: Nucleic acids of defined sequence are detected by hybridisation with two single-stranded nucleic acid probes which are complementary to different regions of the nucleic acid to be detected and are present in the same solution phase, where one nucleic acid probe acts as detector probe and contains at least one hapten as label bound by a chemical linkage, and the other nucleic acid probe acts as trapping probe and is bound to a solid matrix, by using as hapten a steroid which is covalently bonded via a bridge at least four atoms long to at least one position on the detector probe which is not involved in the hydrogen bonding with the nucleic acid to be detected, and by incubating the nucleic acid which is to be detected and is present in solution with the detector probe and the trapping probe in any desired sequence, where the binding of the trapping probe to the matrix is carried out before, during or after the incubation with the nucleic acid to be detected, and by separating the remaining solution from the matrix-bound complex of trapping probe, nucleic acid to be detected and detector probe, and by detecting the complex via an anti-hapten antibody which is labelled in its turn. <IMAGE>

Abstract: The invention disclosed herein provides a panic exit device (20) for doors having in their active side vertically operating bolts extending from the top and bottom of the door and a mechanism (50) for retracting the bolts. Usually, the retracting mechanism may be activated by using a key in an exterior door lock or by depressing a panic bar on the interior of the door. The improved panic exit device of this invention provides a device for actuating the bolt retraction mechanism which is mounted inside a semi-hollow enclosure which is integral with the door. The mounting is accomplished with screws hidden from view by the glass pane securing mouldings. The panic exit device of the invention also provides an improved dogging mechanism to lock the actuator device in the actuated position, while simultaneously preventing excessive play in the panic bar.

Abstract: Disclosed herein is a non-homogeneous immunoassay for measuring an antigen or antibody in a sample solution by reacting the antigen or antibody with a corresponding antibody or antigen immobilized on a solid adsorbent in the presence of a labelled antigen or antibody, wherein the labelled antigen or antibody in a liquid phase is detected and measured after completion of the reaction. 
     This method eliminates a separation step of the solid and liquid phases after completion of the reaction, which had been a bottle-neck for automating the assay, capable of achieving an automation without need for special apparatus.

Abstract: In a radiation detector (11), the electromagnetic radiation (14) incident on a pyroelectric sensor (16) is periodically interrupted. For this purpose, an armature (22) having permanent magnets (23) fastened to the two end faces is arranged at the base (24) of a diverting device (25). If the flow of current in the coil (19) changes periodically, the armature (22) executes a corresponding periodic movement. Consequently, the radiative flow to the pyroelectric sensor (16) is interrupted with the aid of an arm (26) at the diverting device (25), in order in this way to obtain an electrical output signal. The sensor (11) is particularly simply constructed, and can be produced from a few components as a mass-produced product. <IMAGE>

Abstract: A dehumidified air generator (10) has a plurality of rotatable absorption columns (12, 14, 16) filled with adsorbents for gen­erating dehumidified air which will be used to dry a plastic material or the like. A directional control valve for switching between adsorbing and regenerating steps in the adsorption columns comprises a slide valve mechanism com­posed of a stator (34, 38) and a rotor (32, 36) slidably held against the stator. The rotor has a plurality of openings defined therein and communicating with inlet/outlet ports defined in side walls of the adsorption columns through tubes (40, 42, 44). By rotating the rotor in synchronism with the adsorption columns, the adsorbing and regenerating steps are switched to dehumidify, with the adsorbents, humid air introduced into the adsorption columns through the directional control valve and also to desorb the adsorbents for regenerating them.

Abstract: An automatic call booking arrangement is disclosed for establishing a booked call between a back party (150) and a forward party (146). A booked call is reserved by storing call booking ticket data regarding the call in a call booking database (117). A call booking scanning (CBS) process system (119) continually scans call booking ticket data to determine whether it is time to establish a booked call. At the time a booked call is to be established, the CBS process sends the call booking ticket data to an automatic call booking (ACB) process (115). In response to receipt of the call booking ticket data, the ACB process uses the data to establish automatically a call between the back party and the forward party.
